WREST-PLANK FOR PIANOS.

SPECIFICATION forming part of Letters Patent No. 465,417, dated December15, 1891. Application filed February 6. 1891. Renewed November 21, 1891.Serial No. 412,686. (No model.]

To an whom it may concern:

Be it known that I, ALANSON H. REED, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Pin-Blocks or\Vrest-Planks for Pianos; and I do hereby declare the following to be afull, clear, and exact description of the same, such as will enableothers skilled in the art to which my invention appertains to make anduse the same, reference being had to the accompanying drawings, forminga part of this specification.

This invention relates to the pin-block or wrest-plank of pianos thatcarry the tuningpins or other devices for the pianostrings.

The object of the present improvement is to provide an improvedconstruction of such pin-blocks or wrest-planks embodying the veryrequisite features of great rigidity to resist fiexure or springing bythe strain of thepianostrings, combined with compactness and lightnessof structure. I attain such object by the construction and arrangementof parts illustrated in the accompanying drawings, in

Whicl1- Figure 1 is a plan View of a pin-block or wrest-plank embodyingmy presentinvention Fig. 2, a cross-section thereof at line as 09.

Similar numerals of reference indicate like parts in both views.

Referring to the drawings, 1 represents the main body or wooden portionof the wrestplank or pin-block thatcarries the tuningpins 2 or othertuning devices, and 2 the archshaped metal stiffening-brace for the sameextending along the under surface of wrestplank and having end webs orflanges 3,that engage the ends of the plank, as shown.

In mypreferred construction the under surface of the wrest-plank will becut away to fit the curved top or arched member at of the brace, and itis preferable to make the said brace of a width equal to the plank, withits lower web 5 or surface plane, so as to readily fit and bear alongits wholelength against the string-plate or other portion of the pianoby which it is supported.

The metal used in forming the brace 2 may be either any suitable castmetal or a suitable wrought metal pressed or forged into the desiredshape, preferably by pressure between suitable dies.

NVhile the particular form of metal bracepiece 2 shown in the drawingsis my preferred construction, yet any other well-known and approvedstrength and rigidity imparting form of the brace-piece may be employedinstead without departing from the spirit of my present invention.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. A wrest-plank for pianos, comprising a main wooden body carrying thetuning devices and an arched metal brace attached to the under side ofsaid wooden body, substantially as described.

2. A wrest-plank for pianos, comprising a main wooden body carrying thetuning devices and an arched metal brace, the lower face of which isplane and its upper face arched, the under face of the plank being cutaway to rest against said arched face of the brace, substantially as setforth.

3. A wrest-plank for pianos, comprising a main wooden body carrying thetuning devices and an arched metal brace attached to the under side ofsaid wooden body and provided with end webs or flanges, against whichthe ends of the plank abut, substantially as set forth.

4. As an improved article of manufacture, an arch-formed brace for pianowrest-planks of pressed wrought metal, substantially as set forth.

In testimony whereof witness my hand this 3d day of February, 1801.
